ROCKWOOL FLEXI® has been designed as a multi-use, dual purpose acoustic and thermal stone wool insulation with a unique flexible edge along one side.

The ROCKWOOL FLEXI® slab is manufactured with the patented flexible edge which ensures a perfect fit is maintained between the insulation and the supporting framework. The insulation is easy to install and can be fitted between fresh timber and will expand into the wider space as the timber dries out and shrinks back. ROCKWOOL FLEXI® is Euroclass A1 non-combustible and provides additional thermal and acoustic benefits in application.

It is suitable for use all over the home, in pitched roof rafters, framed external walls, internal partitions, intermediate floors, separating walls and floors, and timber suspended ground floors.
